Embodiment 1
[0023] With flax short fiber as raw material, the specific process is as follows:
[0024] (1) Pretreatment - scouring one bath Pretreatment: peracetic acid 3.0g / L, sodium silicate 2.0g / L, temperature 55°C, time 45min, bath ratio 1:30; sodium carbonate 9.0g / L, silicon Sodium acid 2.5g / L, temperature 95°C, time 50min;
[0025] (2) Hot water washing: wash twice at 85-90°C;
[0026] (3) Warm water washing: wash twice at 45-50°C;
[0027] (4) Dehydration: 3 to 5 minutes;
[0028] (5) Dyeing: Reactive dye KE1.0%, rubbing fastness improver NEOFIXIR-770.08g / L, dyeing at 50°C, adding sodium chloride 20.0g / L, heating to 90°C at 1°C / min, adding carbonic acid Sodium 6.0g / L, keep warm for 55min, liquor ratio 1:30;
[0029] (6) Washing in cold water: wash twice at 20-30°C;
[0030] (7) Soap boiling: soap flakes 2.0g / L, sodium carbonate 2.0g / L, temperature 95°C, time 8min, liquor ratio 1:30;
[0031] (8) Washing in cold water: washing at 20-30°C until alkali-free;
[0032] (9) Dehydr...
